International Schools in Brussels

Ages 2-18 · IB, American · Watermael-Boitsfort · ~1,350 students

ISB is the right call for families who want genuine inclusion alongside strong IB results, and who value the stability that comes from being the oldest and only truly independent not-for-profit English school in Brussels. The campus at Kattenberg is large and green, though it is less convenient from the city centre than some alternatives.

Ages 3-18 · British, IB · Tervuren · ~1,200 students

If you want the best IB results in Belgium with no development levy and a genuinely international campus, BSB is the standout choice. The location in Tervuren is 20 minutes from central Brussels - assess whether that commute works for your family before committing.

Ages 1-18 · IB · Waterloo · ~500 students

St. John's is worth serious consideration for families who want the full IB continuum from early years through Diploma in a smaller, more personal school - and it is the only option in Belgium for families who need boarding. The Waterloo location is a genuine consideration if you are based in Brussels proper.

Ages 2.5-18 · IB · Uccle & South · ~300 students

BEPS suits families who want the full IB offering - including the rare Career-related Programme - in a genuinely small school near the Bois de la Cambre. It is not the right choice if you need a large campus, published exam results, or the lowest corporate-tariff fees.

Ages 1-18 · IB, Montessori · Other Brussels · Contact school students

If you want genuine Montessori pedagogy for the early and primary years, followed by a structured IB pathway through secondary, IMS Brussels is the only school in the region that offers both coherently. The fees are at the top of the Brussels market at standard tariff - ask the school about the reduced tariff if you are self-paying.

Ages 5-19 · IB · Central Brussels · ~200 students

Montgomery suits families who want a small, genuinely bilingual IB school in central Brussels with a strong track record - 100% IB pass rate for seven years - and can accept the limited physical campus that comes with a converted townhouse. It is not the school for families who want wide subject choice or large co-curricular programmes.

Ages 3-16 · British · Central Brussels · ~300 students

BJAB is the right call for families in Etterbeek, the EU quarter, or central Brussels who want a small British-curriculum school with reasonable fees and a personal community feel. The IGCSE offering is solid; check the IB Diploma timeline with admissions if your child will reach Year 12 soon, as the programme launches in August 2026.

Ages 2-11 · British · Diegem & North · ~150 students

BISB is an excellent primary school - but plan secondary before you enrol. Families who need continuity through to 18 will need a second school from age 11; that is not a weakness but it is the defining practical decision.

Ages 2.5-18 · British · Waterloo · ~300 students

ISF Waterloo is a sound choice for families based along the Waterloo corridor who want a small British-curriculum school with strong pastoral care, IGCSE, and A-Levels at fees meaningfully below BSB or ISB. Families based in central Brussels or north of the city should check the commute carefully before enrolling.

Ages 3-18 · IB · Uccle & South · ~550 students

If the Uccle South campus suits your commute and you want the full IB continuum at fees well below BSB or ISB, Bogaerts is a credible choice. Families near NATO in Diegem have the North Campus as a closer option - ask admissions which campus your child would attend before enrolling.

Ages 2-18 · IB · Tervuren · ~210 students

The Courtyard is the standout choice in Brussels if you want the full IB continuum - all four programmes - in a genuinely small school, with bilingual education in your choice of two languages from English, French, and Dutch. The Tervuren location is ideal for families near BSB, NATO east, or Leuven.

Ages 2-18 · British · Central Brussels · ~600 students

BICS suits families who want affordable bilingual education with Catholic values at fees well below the Brussels mainstream - but verify A-level outcomes directly with the school before enrolling at secondary level.
